Seoul in year 1922 The school was first opened as Kwangsŏngŭisuk () in 1904 by , nephew of
Empress Myeongseong. It was run out of his home, with an initial class size of 30 students. In 1914 Whimoon Euisuk became Whimoon Private Normal School and then became Whimoon Middle School in 1928, in line with the changing educational policies of the era. During the
Japanese colonial era, the school silently played a role in the
Korean independence movement by continuously teaching the Korean language despite it being banned by the colonial government. It first became known for its liberal school culture, an extensive sports program and placing equal emphasis on humanities and liberal arts alongside languages and the sciences. At that time, all schoolboys had to keep a military-style buzz cut and had to abide by a very strict dress code. However, Whimoon did not require its boys to adhere to that mandated hair and dress code. Instead, their students were only expected to maintain a neat appearance and had several types of uniforms to choose from, which was unheard of. The unique school culture would persist into the 1970s. Initially Whimoon was a six-year school. With the 1957 government policy of "3+3" (3 years of middle school and 3 years of high school), Whimoon was legally split into two separate schools: Whimoon Middle School and Whimoon High School. Both schools still maintain an affiliation, with a large number of alumni from the post-war years having attended both schools. Originally, the location of the school was middle of Seoul (
Jongro-gu). In 1977 and 1979 both schools moved to their current locations in Gangnam, across the
Han River. In 2010, it became a self-governing (private) school. In 2018 an audit by the
Seoul Metropolitan Office of Education revealed that Whimoon Euisuk, the school corporation containing Whimoon Middle and High School, as well as its honorary chairman, embezzled from renting the school building as a place of worship for a church. == Admissions ==
